The last time to the track was with just a lid, hooker cat back, and Pace MAF. I ran a 13.3x @ 106.60 with 315rwhp and 328rwtq. That was in the summer. Since then I have added 4.10's, ls6 intake, ported TB, and off dyno tune. Now it is winter. What do you guys think those mods will be worth. I will find out the hard results tomorrow but was wondering what they have been worth for others. I just hope it doesn't rain. I was hoping to go 12.90 @ 108+. Am I reaching?
